Shelley Pratt was told: “Please come home, your Christmas presents are waiting for you under the tree.”

The 14-year-old disappeared five weeks ago after she was seen chatting to a man.

Mum Lisa said yesterday: “Shellz, please get in touch with us. We are desperate to hear your voice and know that you are safe and well.

“You’re not in trouble. We love you and we miss you and just want you home. Without you there will be no Christmas. We are all missing you like mad. We love you, please, please come home. Your presents are under the tree.”

Police have launched a big campaign to find Shelley, releasing CCTV footage of her last known movements. It shows the teenager, from Norwood, south London, in an “I love London” hoody.

In one image she is talking to a young black man in Croydon High Street around midnight on Friday, November 9.

Her travelcard was then used to board a bus heading to nearby Coulsdon. Shelley’s dad Tony said: “I want to give her the biggest kiss and cuddle she’s ever had. I’ve been out every night on my bike looking for her.

“Whether it’s snowing or raining, I’m there. She loves Christmas, she would never miss it.”

Detective Chief Inspector Mark Dunne said the amount of time Shelley has been missing was a cause for concern.

He added: “She has had no contact with friends or family. We have received a number of unconfirmed sightings but I urge anyone who may have seen Shelley to contact us.”
